Ocular ultrasound versus MRI in the detection of extrascleral extension in a patient with choroidal melanoma.

BACKGROUND: To describe the superiority of ocular ultrasound in the diagnostic management of extrascleral extension in choroidal melanoma. CASE PRESENTATION: We present a case of a 94-year-old male with choroidal melanoma of the right eye imaged with MRI and ocular ultrasound to aid in the detection of extrascleral extension. CONCLUSIONS: With advancement in technology and new imaging modalities emerging, it can become difficult to determine the best diagnostic approach for patients. We believe that ocular ultrasound remains the superior imaging modality in detection of extrascleral extension in choroidal melanoma.

The ophthalmic fallout in Utah after the Great American Solar Eclipse of 2017.

BACKGROUND: Solar retinopathy is a rare ophthalmic disorder resulting from sustained viewing of the sun without protective eyewear. Incidence of solar retinopathy typically increases following a solar eclipse due to attempted visualization of the sun without appropriate eye protection. This paper serves as a case series of all available reported cases of solar retinopathy present in Utah resulting from the August 21st, 2017 solar eclipse. METHODS: Twenty-seven patients had presented with concern for vision changes after the solar eclipse and six patients had exam findings consistent with solar retinopathy. Of these six cases, charts were available for three. RESULTS: The common finding in all cases was a central scotoma with a correlating change to the inner segment/outer segment junction on optical coherence tomography. Demographically, all three patients were young males. CONCLUSION: This data provides insights on populations in Utah at risk for ophthalmic damage and can aid in targeting education programs in the future.
